To all 'whom fit-may concern:

y M. HEYMAN, acitizen vof theUnited States,l residing at Brooklym'county of Kings, State of New York, have invented certain new and usefu Improvements 'in Controllii'igValves for Combustible Liquids, of Which thefollovving-is va full, clear, and exact description. This" invention relates to a controlling valve for combustible liquids such as gasolene, naphtlia, benzin, or any other liquid which lets olf combustible vapors.

i The object of this valve is to provide a device which is adaptedl to admit air pressure to a receptacle containing the liq to be drawn therefrom, to permit lnthe drawings-Which form part of this.

4l illustrates a section of' my improved valve, and also a connected receptacle in` elevation; and Fig. Q is an enlarged top plan view ot the valve.v

My improvement may be carried out in any 'one of a variety of Ways, the form here'- in yillustrated being preferable. As herein illustrated my improved valve comprises a :casing 1, provided `With a valve proper, in-

under provided thereinto, a spigot 9. r.lhe lug S receives the end of a pipe 10 which leads fromasupply of air under pressure. The valve proper, 2 is provided with passages 11, V12 and 13. The'passage 11 alines ,with the openings in the casing 1, which communicate with the supply pipe 5I and spigot 9 and the passage 12 ralines with the openings in lt-hel ca'sing `1',

which communicate with the air inlet pipe l0 and pipe 6, when the valve 1 is turned for the purpose of drawing oli the contents of the tank 6a. l y

The passage 13 is a vent and alines With the openings 14 and 15 inthe valve casing, when the valve is shuty by-pass 16. Stop pins '17 'on the valve cas-v ing limit they movement of the liaiidle 18, on the valve 2, for the open andclosed positions.

Havingnoiv described my invention,y what I. claim and desire to secure by Letters Patcnt is:

n combination lwith. a receptacle for com-A bustible liquids, a controlling valve comprising a casing, an air inlet, an outlet and a. vent passage, a pipe connecting said air inlet with said receptacle, a pipe connecting said outlet, and. said receptacle, a pipe connectiiig'said vent passage with said air pipe,

off, so as to allow the. gases in the tanka to flow off, through the.

and a valve in said casing provided with a passage adapted to aline with said air inlet, a passage adapted to aline with said inlet and a passage adapted to aline with said. vent when said inlet and l'outlet are shut oil'. Signed at New York city, N. Y; this E24 day of April 1912.
